摘　　要：针对无线网络服务能耗较高的问题,提出了一种基于机会主义的能量感知调度方案(OEARS)。首先,该方法将资源分配过程中的能耗和其他自然因素同时考虑,采用一种称为MAC/PHY机会主义方法对系统吞吐量进行优化;然后,利用唤醒-休眠模式和信道条件进行实现能耗最小化,并利用物理层信息提高系统容量,最大化能量效率。仿真实验结果表明,在保持接近的系统性能的前提下,OEARS的能耗低于现有的其他调度方案。Aimed at the problem of high energy consumption of wireless network service, an energy-aware resource scheduling scheme-OEARS based on the opportunism is proposed. Firstly, this method considers the energy consumption and other natural factors in the process of resource allocation. An opportunistic approach called MAC/PHY is used to optimize the system throughput. Then, the energy consumption is minimized by using the wake-sleep mode and the channel condition, and the physical layer information is used to improve the system capacity and maximize the energy efficiency. The simulation results show that the energy consumption of OEARS is lower than that of other existing scheduling schemes on the premise of keeping the close system performance.
